PURPOSE:To obtain a herbicide, containing an N-[1-(thienyl)ethyl]amine derivatine, pyrazole derivative and chloramide or cumylurea derivative, usable in any periods without phytotoxicity to paddy rice and having an extended weeding spectrum. CONSTITUTION:A herbicidal composition, containing a compound expressed by formula I [Z is halogen, lower alkyl, etc.; n is 0, 1 or 2; R is formula II (X and Y are H, alkyl, etc.), etc.], a compound expressed by formula III (R<1> is H or CH3; R<2> is formula IV, etc.; Q is CH3 or Cl; k is 0-3) and a compound expressed by formula V [R is expressed by the formula -CB(Br)-C(CR3)3, etc.] and adjusted so as to respectively apply 30-300g compound expressed by formula I, 90-300g compound expressed by formula III and 30-300g compound expressed by formula V by weight ratios per 10 ares. This composition is usable in any period simultaneously or just after seeding or transplanting to growth period of weeds in paddy field without phytotoxicity and capable of controlling annual, perennial weeds to duckweeds and algae. |
